Test native Codex agent behavior or audit rollout evidence for lifecycle, tool use, and skill invocation. Use for agent-runtime claims, not ordinary task validation.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Native agent evals Define one observable claim with pass, fail, and inconclusive outcomes. Choose a small probe that can falsify it. Keep production mutations outside the probe unless explicitly requested. ## Run a probe Before running native agents, load [native-subagents-first](../native-subagents-first/SKILL.md) for the lifecycle and worker contract. Exercise only the behavior under test: tool availability, completion, waiting, fanout, interruption, resume, or skill invocation. For example, fanout needs independent scopes; a lifecycle check may need only one harmless child. For comparisons, hold model, effort, role, tools, prompt, permissions, and artifact state fixed. Change only the named treatment. Mark mismatched conditions as confounded. Repeat independent behavior comparisons before promoting a claim. Consume the complete child answer and verify its relevant evidence. Lifecycle status alone does not prove that the requested task succeeded. ## Audit or export evidence …

How to install
mdr add kbediako/evergreen-codex-skills/native-agent-evals@sha256:48e18902d93649c0The line at the top of this page pins the label git:20260912.7ff2e86, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
